(Second Embodiment) Next, a second embodiment of the present invention will be described with reference to FIG. In the following embodiments, when the configuration is the same as that of the embodiment described above, the same reference numeral is assigned and the description is omitted.

FIG. 3 shows a locking mechanism 2 according to this embodiment.
6 is shown. Here, the locking receiver 27 constituting the locking mechanism 26 is entirely formed of a metal plate, and is provided on a substantially rectangular plate-shaped fixing plate 28 with the same locking piece 20 as that of the first embodiment. (See FIG. 3B). And, the lock receiving device 27
Screws or the like are fixedly arranged inside the left edge of the outer frame 11 so that the locking pieces 20 are located on the front side of the machine. The fixing plate 28 and the locking piece 20 have substantially the same length in the longitudinal direction, and the upper end surface 28a of the fixing plate 28 is engaged with a protective cover 30 described later. Projection 29
Are formed.

Next, the protective cover 30 as a shielding means in the present embodiment will be described. The protective cover 3
Reference numeral 0 denotes an upper protection plate 30a, which is formed entirely of a metal plate and has a substantially rectangular side protection plate 30a.
b, the lower protection plate 30c and the front protection plate 30d are integrally formed. The upper protection plate 30b
, And a lower flange 30c is integrally formed with a second flange 30f. As shown in FIG. 3A, the protective cover 30 is formed to have a size capable of surrounding the locking piece 20 and the locking hook 21 when the locking mechanism 26 is locked.

The protective cover 30 is rotatably mounted on the inner side of the left edge of the outer frame 11 by a pin 31 at the second flange portion 30f. Further, the first flange portion 30e has a protrusion 2 formed on the fixing plate 28.
9 is formed with a locking groove 32 that can be engaged and disengaged. Therefore,
The protective cover 30 is provided on the protrusion 29 of the lock receiver 27.
And the shielding position where the locking groove 32 of the protective cover 30 is engaged (see FIG. 3A), the protrusion 29 and the locking groove 32
3 (b) can be freely rotated and displaced. That is, the external operation member 46 is prohibited from contacting the locking hook 21 when the protective cover 30 is at the shielding position, and is allowed to contact the locking hook 21 when the protective cover 30 is at the non-shielding position. Will be.

Next, the locked state and the unlocked state of the locking mechanism 26 will be described. First, in order to lock the locking mechanism 26 as shown in FIG.
It can be performed in the same procedure as in the first embodiment. When the protective cover 30 is in the shielding position, the external operation member 46 that has entered is prohibited from coming into contact with the locking hook 21 from the tip direction, the vertical direction, and the right side direction. Therefore, the external operation member 46 performs the operation 3 shown in FIG.
As described above, the locking hook 21 cannot be brought into contact with the locking hook 21, so that an illegal external operation becomes impossible and the locking mechanism 26 cannot be unlocked.

In this embodiment, the locking mechanism 26 can be unlocked in the same procedure as in the first embodiment. Further, when a lock for performing a locking operation on the locking device of the pachinko machine is lost, first, the adjacent pachinko machine is unlocked from the front side by another lock, and then the front frame 12 is unlocked. To the outer frame 11. Then, the arm is inserted from the front side of the pachinko machine, and the protective cover 30 is rotated to the non-shielding position. Then, as shown in FIG. 3 (b), the distal end side of the locking hook 21 is in an open state, so that a fingertip is hung on the locking hook 21 and the locking hook 21 rotates downward. Apply force as you can. Then, the locking hook 21 operates in the same manner as the locking operation from the front side of the machine and comes off the locking piece 20, so that the locking mechanism 26 can be in the unlocked state.

Thereafter, after maintenance of the inside of the machine is performed, the protective cover 30 is rotated to the shielding position, and the projection 29 is engaged with the locking groove 32, so that the external operation member is locked. It is possible to prohibit the contact of the hook 46 with the locking hook 21. Then, the locking mechanism 26 is changed from the unlocked state to the locked state in the same procedure as in the first embodiment.

Therefore, according to the present embodiment, the following effects can be obtained. (3) Since the locking hook 21 is surrounded by the protective cover 30 in the locked state, the external operating member 4
6 can be prohibited from contacting the locking hook 21 in multiple directions. Therefore, it is possible to reliably prevent improper operation due to improper external operation.

(4) Since the protective cover 30 is rotatably mounted on the outer frame 11, even if the lock for performing the locking operation is lost, the locking mechanism 26 can be easily operated from the adjacent pachinko machine. Can be unlocked.

(Third Embodiment) Next, a third embodiment of the present invention will be described with reference to FIG. In the present embodiment, the external operation member 46 is allowed to come into contact with the locking hook 21, and the external operation member 46 is locked in order to prevent improper operation due to improper external operation. It is based on the idea of restricting operation in the direction to release the state. Therefore, this is different from the first and second embodiments in which the contact with the locking hook 21 is completely prohibited.

FIG. 4 shows a locking mechanism 3 according to this embodiment.
3 is shown. The lock receiver 34 of the present embodiment is different from the lock receiver 27 of the second embodiment only in that the projection 29 is not formed on the fixing plate 35, and the basic configuration is the same. Have been.

The protective piece 36 as the regulating means in the present embodiment is entirely formed of a metal piece, and the tip protective piece 36a and the side protective piece 36b are integrally formed in a substantially L-shape. I have. In addition, the protective piece 36 protrudes vertically from the lower side of the lock receiving member 34 toward the inside of the machine on the inner side of the left edge of the outer frame 11. It is attached to surround the side. Further, the vertical position where the protective piece 36 is mounted is substantially the same as the distal end side of the locking hook 21 in the locked state.

Here, when the protective piece 36 is mounted below the distal end of the locking hook 21, the operation of the external operating member 46 in the direction of releasing the locked state is restricted. May not be possible. That is, there is a possibility that the locking hook 21 may come off the locking piece 20 before the external operating member 46 comes into contact with the protective piece 36.
However, even if the protection piece 36 is mounted on the lower side, the vertical distance between the tip side of the locking hook 21 and the protection piece 36 is greater than the length in the depth direction of the groove 25 of the locking hook 21. When the distance is short, the unlocking operation by the external operation member 46 can be restricted.

On the other hand, the protection piece 36 is
When the external operation member 46 is mounted above the distal end side of the first operating member 1, the operation of the external operating member 46 in the direction of releasing the locked state cannot be restricted. That is, the external operating member 46 is brought into contact with the locking hook 21 through a gap between the distal end side of the locking hook 21 and the protective piece 36, whereby the external operating member 46 is formed.
Can be operated in the direction to release the locked state.

Further, the side protection piece 36b constituting the protection piece 36 is arranged in a state where a gap with the locking hook 21 is hardly formed. That is, the protective piece 36 is protruded toward the inside of the machine such that the side protective piece 36b is positioned with almost no gap from the side of the locking hook 21 in the locked state. Therefore,
For example, the projection 49 of the external operation member 46 shown in FIG.
Even when the external protection member 36b is configured to extend thinly in the vertical direction, the side protection piece 36b abuts on the tip (projection piece 49) of the external operation member 46, so that the locking state is released. Operation can be regulated.

Next, the locked state and the unlocked state of the locking mechanism 33 will be described. First, as shown in FIG. 4, in order to lock the locking mechanism 33, the first
Can be performed in the same procedure as in the embodiment.

Then, in the locked state, when the external operating member 46 enters from the gaps S1 and S2 of the pachinko machine 10, the locking hook 2 is moved as shown in an operation 3 shown in FIG.
The projecting piece 49 of the external operation member 46 can be brought into contact with the distal end of the first operating member 46. Therefore, if the external operation member 46 is operated downward, the locking hook 21 can be rotated downward. However, before the locking hook 21 is disengaged from the locking piece 20, the protruding piece portion 49 comes into contact with the protective piece 36, so that the downward movement of the external operating member 46 is restricted by the protective piece 36. Is done. Therefore,
The locking hook 21 does not come off the locking piece 20, and the locking mechanism 33 is not unlocked.

In this embodiment, the locking mechanism 3
In order to make the unlocking state of the lock 3, the same procedure as in the first and second embodiments can be performed. Therefore, according to the present invention, the following effects can be obtained.

(5) The external operation member 46 is formed by the protection piece 36.
Because the movement in the direction to release the locked state is regulated,
Unlocking of the locking mechanism 33 due to an improper external operation can be prevented.

(6) The lock mechanism 33 can be made inexpensive because it has a simple configuration in which only the protective piece 36 is provided. The first to third embodiments may be modified as follows.

In the first embodiment, the protection plate 23 is formed integrally with the lock receiving member 18, but the protection plate 23 is formed separately from the fixing plate 22. May be rotatable with respect to the outer frame 11 as in the protective cover 30 in FIG. Even with such a configuration, the same effects as (1) and (4) of the above embodiment can be obtained.

In the first embodiment, the protection plate 23 is provided on the tip end of the locking hook 21. However, the protection plate 23 may be provided on the upper side, lower side or side surface of the locking hook 21. . Further, for example, the protection plate 23 may be provided in a combination such as a tip side and an upper side. Even with such a configuration, the same effects as (1) to (3) of the embodiment can be obtained.

· Locking piece 2 in the first embodiment
0, longitudinal direction (vertical direction) of fixed plate 22 and protective plate 23
The length in the lateral direction is not limited to the length described in the embodiment. For example, the locking piece 20 and the fixing plate 22 may have the same length, or the tip of the locking hook 21 may not be located substantially at the center of the protective plate 23 in the short direction. That is, the dimensions of these members 20, 22, and 23 are appropriately changed according to the design specifications of the gaming machine. Even with such a configuration, the same effects as those of the above-described embodiment can be obtained. The same applies to the locking piece 20 and the fixing plate 28 in the second embodiment.

The protective cover 30 in the second embodiment and the protective piece 36 in the third embodiment may both be provided on the outer frame 11. With this configuration,
In addition to the effects (3) to (6) of the above embodiment, even if the user forgets to set the protective cover 30 at the shielding position, the protective piece 36 can prevent the external operation by the external operation member 46. it can.

In the third embodiment, the protection piece 36 is formed in an L-shape. However, two sets of the side protection pieces 36b are formed in a U-shape, and both sides of the locking hook 21 are formed. The part may be surrounded. With this configuration, in addition to the effects (5) and (6) of the above-described embodiment, the operation of the external operation member 46 can be more reliably restricted.

In the third embodiment, the protection piece 36 is formed in an L-shape. However, the protection piece 36 may protrude only from the tip end of the locking hook 21. According to this structure, (5) and (6) of the above embodiment
It has the same effect as.

Contrary to the above embodiments, the locking piece 20 is formed outside the left edge of the front frame 12 and the locking hook 21 is connected to the outer frame 1.
